† Notice: Stresses above those listed under “Maximum Rat-

ings” may cause permanent damage to the device. This is a

stress rating only and functional operation of the device at

those or any other conditions above those indicated in the

operational listings of this specification is not implied. Expo-

sure to maximum rating conditions for extended periods may

affect device reliability.

DC CHARACTERISTICS

Electrical Specifications: Unless otherwise indicated, all limits are specified for VDD = 1V to 5.5V, RPU = 100 kΩ

(only MCP1320, MCP1321, and MCP1322), TA = -40°C to +125°C.

Note 1:

Trip point is ±1.5% from typical value.

Trip point is ±2.5% from typical value.

Hysterysis is minimum = 1%, maximum = 6% at +25°C.

This specification allows this device to be used in PIC® microcontroller applications that require the In-Cir-

cuit Serial Programming™ (ICSP™) feature (see device-specific programming specifications for voltage

requirements). The total time that the RST pin can be above the maximum device operational voltage

(5.5V) is 100s. Current into the RST pin should be limited to 2 mA. It is recommended that the device oper-

ational temperature be maintained between 0°C to +70°C (+25°C preferred). For additional information,

refer to Figure 2-35.

This parameter is established by characterization and is not 100% tested.

Custom ordered voltage trip point; minimum order volume requirement. Information available upon request.
